Description
Technical Field
[0001] This application relates to the technical field of automotive component testing, and in particular to a waterproof sealing test device for a window control module. Background Technology
[0002] As a key component of automotive electronic systems, the window control module is primarily used to implement window raising and lowering control, locking status management, and safety functions such as anti-pinch protection. It integrates precision circuits, sensors, and drive components, and is typically installed inside the door near the window rails. During daily vehicle use, it may be threatened by rainwater infiltration, car wash sprays, or accidental water immersion. Water exposure to the window control module can cause short circuits, component corrosion, or malfunction; therefore, its waterproof and sealing performance must be rigorously evaluated during research and development and production.
[0003] To simulate the water-related scenarios of the window control module in real-world conditions, existing technologies typically employ immersion tests and water spray tests. These two types of tests address the waterproofing requirements of different usage scenarios. The immersion test simulates a vehicle wading through water or accidentally falling into water by immersing the window control module in water, thus verifying its sealing performance in a static water environment. The water spray test simulates dynamic water impact scenarios such as driving in the rain or washing a car by spraying water onto the module's surface, thus evaluating its resistance to water penetration.
[0004] Regarding the aforementioned technologies, since immersion testing and water spray testing need to be completed separately in independent immersion test chambers and water spray test stands, the samples must be disassembled, transported, and re-clamped manually during the testing process. This process results in low testing efficiency. Therefore, how to integrate immersion and water spray testing into the same device and avoid the efficiency loss caused by manual transport has become a key technical bottleneck for improving the reliability of waterproof testing of vehicle window control modules. Utility Model Content
[0005] In view of the shortcomings of the existing technology, one of the purposes of this utility model is to provide a waterproof sealing test device for vehicle window control modules.
[0006] This application provides a waterproof sealing test device for a vehicle window control module, which adopts the following technical solution:
[0007] The waterproof sealing test device for a vehicle window control module includes a housing, a spray assembly for spraying water onto the vehicle window control module, and a fixing assembly for placing the vehicle window control module. The fixing assembly is rotatably installed at the bottom of the housing, and the spray assembly is fixed to the side wall and top of the housing, with the spray range covering the surface of the vehicle window control module. The bottom of the housing is connected to a drainage pipe for draining water accumulated inside the housing and a water inlet pipe for injecting water into the housing.
[0008] By adopting the above technical solution, the spray components are distributed on the side walls and top of the chamber, and together with the rotatable fixing components, the water spray test can simulate the rain washing environment 360° without dead angles, so that the water flow can evenly cover all surfaces and gaps of the window control module, and accurately test the waterproof sealing performance under dynamic spraying. During the immersion test, a static immersion space can be quickly created by closing the drain pipe and opening the water inlet pipe, so that the window control module is completely submerged in water, which meets the immersion scenario test requirements of waterproof sealing test. The free switching between the two test modes does not require disassembling the workpiece or using multiple sets of equipment, but can be achieved by simply controlling the drain pipe and the water inlet pipe, which significantly improves the test efficiency.
[0009] Preferably, the spray assembly includes a spray head and a spray pipe. The spray pipe is fixed to the side wall and top wall of the housing. One end of the spray head, which is used for spraying, faces the window control module, and the other end of the spray head, which is away from the spraying end, is connected to the spray pipe.
[0010] By adopting the above technical solution, the spray head facing the window control module can spray water from different directions. With the rotation of the fixed component, the water can evenly impact all corners of the window control module surface, accurately simulating waterproof scenarios under complex water environments such as natural rainfall or high-pressure washing, and effectively testing the sealing performance of the window control module under dynamic water flow impact.
[0011] Preferably, the spray pipe is equipped with a water pump for adjusting water pressure, and the water pump is located in the spray pipe away from the spray head.
[0012] By adopting the above technical solution, when the water pump operates at low power, it slowly pressurizes the water flow and sprays it out through the spray nozzles, simulating natural rainfall and effectively testing the sealing performance of the window control module under normal rain conditions. When the water pump operates at high power, it increases the water pressure, causing the spray nozzles to spray a strong water jet. Combined with the layout of vertical downward spray from the top and oblique spray from the side walls, it simulates the strong water flow scouring scenario during a high-pressure car wash, testing the waterproof reliability of the window control module under extreme water pressure. By adding a water pump, the cumbersome operation of frequently changing tooling or adjusting the structure required by traditional testing equipment for different scenarios is avoided, significantly improving testing efficiency and equipment utilization.
[0013] Preferably, the fixing component includes a pneumatic gripper and a rotating shaft. A rotating cylinder is provided at the bottom of the housing. The rotating shaft is rotatably connected to the rotating cylinder. The end of the rotating shaft away from the rotating cylinder is fixedly connected to the pneumatic gripper. The end of the pneumatic gripper away from the rotating shaft clamps and fixes the window control module.
[0014] By adopting the above technical solution, the pneumatic gripper's precise clamping of the window control module ensures that the workpiece does not shift or shake during the test, avoiding deviations in water flow detection caused by unstable clamping. The rotary cylinder drives the rotary shaft to rotate the window control module at a preset speed, so that the water flow from the spray component can cover all surfaces of the module 360° without dead angles, ensuring that the window control module undergoes comprehensive waterproof testing under dynamic water flow impact or static immersion.
[0015] Preferably, the pneumatic gripper has an anti-slip silicone pad on its inner side.
[0016] By adopting the above technical solution, the anti-slip silicone pad can closely fit the irregular contours of the window control module surface due to its flexible fit and high friction performance. By increasing the frictional resistance of the contact surface, it effectively counteracts the displacement trend caused by the impact of strong water flow, ensuring that the window control module always maintains accurate positioning during high-speed rotation or high-pressure spraying, and avoiding uneven coverage of the detection area caused by the shaking of the window control module.
[0017] Preferably, the drainage pipe is equipped with a valve for switching the drainage pipe on and off, a water storage tank is provided at the end of the drainage pipe away from the box, and the end of the spray pipe away from the spray head is connected to the water storage tank.
[0018] By adopting the above technical solution, the valve controls the opening and closing of the drainage pipe. After testing, the water flows back to the storage tank through the drainage pipe, forming a closed loop connected to the spray pipe. This avoids the water waste caused by the one-time drainage of traditional testing equipment. During immersion testing, closing the valve can block the water circulation, allowing the chamber to quickly form an independent static immersion space. After the test, opening the valve again returns the water to the storage tank, reserving water for the next test and reducing the frequent access of external water sources. The dynamic spray and static immersion testing modes are switched only by opening or closing the valve, significantly improving the versatility of the waterproof sealing testing device.
[0019] Preferably, the drainage pipe is provided with a filter screen for filtering impurities at the bottom of the box.
[0020] By adopting the above technical solution, the filter screen can effectively capture large particulate impurities in the test water, preventing large particulate impurities carried in the water flow from entering the spray pipe or spray head with the circulating water, preventing problems such as unstable water flow pressure and spray angle deviation caused by pipe blockage, and ensuring that the spray component always accurately simulates different water flow scenarios with the set pressure and angle.
[0021] Preferably, the spray pipe is equipped with a buffer water tank located outside the water storage tank. The bottom of the buffer water tank is connected to the water storage tank through the spray pipe, and the top of the buffer water tank is connected to the water pump through the spray pipe.
[0022] By adopting the above technical solution, the bottom of the buffer water tank is connected to the water storage tank to replenish water in real time, and the top is connected to the water pump to form a pressure transition zone. When the water pump draws water from the water storage tank, the water stored in the buffer water tank can provide a stable water flow in advance, effectively alleviating water pressure fluctuations caused by the start-up or power adjustment of the water pump, ensuring that the spray head always sprays water at a uniform pressure, and accurately simulating scenarios such as natural rainfall or high-pressure car washing.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The spray components are distributed on the side walls and top of the chamber. Together with the rotatable fixing components, they can simulate the rain washing environment 360° without dead angles during water spray testing, so that the water flow can evenly cover all surfaces and gaps of the window control module, accurately testing the waterproof sealing performance under dynamic spraying. During water immersion testing, a static water immersion space can be quickly created by closing the drain pipe and opening the water inlet pipe, so that the window control module is completely submerged in water, meeting the water immersion scenario testing requirements for waterproof sealing. The free switching between the two test modes does not require disassembling the workpiece or using multiple sets of equipment. It can be achieved simply by controlling the drain pipe and the water inlet pipe, which significantly improves the testing efficiency.
[0025] 2. The spray nozzles facing the window control module can spray water from different directions. With the rotation of the fixing components, the water can evenly impact all corners of the window control module surface, accurately simulating waterproof scenarios under complex water environments such as natural rainfall or high-pressure washing, and effectively testing the sealing performance of the window control module under dynamic water flow impact.
[0026] 3. When the water pump operates at low power, it slowly pressurizes the water flow and sprays it through the spray nozzles, simulating natural rainfall to effectively test the sealing performance of the window control module under normal rain conditions. When the water pump operates at high power, it increases the water pressure, causing the spray nozzles to spray a strong stream of water. Combined with the vertical downward spray from the top and the oblique spray from the side walls, it simulates the strong water flow scouring scenario of a high-pressure car wash, testing the waterproof reliability of the window control module under extreme water pressure. By adding a water pump, the cumbersome operation of frequently changing tooling or adjusting the structure required by traditional testing equipment for different scenarios is avoided, significantly improving testing efficiency and equipment utilization.

[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 2 This application will be described in further detail.
[0031] This application discloses a waterproof sealing test device for a vehicle window control module.
[0032] Reference Figure 1 and Figure 2 A waterproof sealing test device for a vehicle window control module includes a housing 1, a door 11 for opening the housing, a spray assembly 2 for spraying the vehicle window control module, and a fixing assembly 3 for placing the vehicle window control module. The fixing assembly 3 is rotatably installed at the bottom of the housing 1. The spray assembly 2 is fixed to the side wall and top of the housing 1, and the spray range covers the surface of the vehicle window control module. The bottom of the housing 1 is connected to a drainage pipe 4 for draining water accumulated inside the housing 1 and a water inlet pipe 5 for injecting water into the housing 1. During the water spray test, the door 11 is opened, and the window control module is fixed to the fixing component 3 inside the housing 1. Then, the spray component 2 is activated, and the spray components 2 distributed on the side walls and top of the housing 1 spray water onto the window control module. At the same time, the fixing component 3 rotates so that the spray range of the spray component 2 fully covers the window control module. While the spray test is underway, the water accumulated inside the housing 1 is drained out through the drain pipe 4. During the immersion test, the drain pipe 4 is closed, and the water inlet pipe 5 is opened to fill the housing 1 with water until the water level covers the window control module, maintaining a static water environment for the immersion test. After the immersion test is completed, the water inside the housing 1 is drained out again through the drain pipe 4.
[0033] Specifically, the sprinkler assembly 2 includes a sprinkler head 21 for spraying water and a sprinkler pipe 22 for connecting to a water source. The sprinkler pipe 22 is fixed to the side wall and top wall of the housing 1. One end of the sprinkler head 21 for spraying water faces the window control module, and the other end of the sprinkler head 21 away from spraying water is connected to the sprinkler pipe 22.
[0034] Furthermore, a water pump 6 for regulating water pressure is installed on the spray pipe 22, and the water pump 6 is located in the spray pipe 22 away from the spray head 21. When a rain test is conducted, the water pump 6 operates at a low power, slowly pressurizing the water source and delivering it to the spray pipe 22. The spray heads 21 on the top and side walls disperse the water flow into fine droplets, simulating natural rainfall. When a high-pressure car wash test is conducted, the water pump 6 increases its power, increasing the water pressure and delivering it to the spray head 21. The top spray head 21 sprays vertically downwards, and the side wall spray head 21 sprays at a certain angle, simulating a high-pressure water gun spraying scenario.
[0035] Specifically, the fixing component 3 includes a pneumatic gripper 31 and a rotating shaft 32. A rotating cylinder 7 is provided at the bottom of the housing 1. The rotating shaft 32 is rotatably connected to the rotating cylinder 7. The end of the rotating shaft 32 away from the rotating cylinder 7 is fixedly connected to the pneumatic gripper 31. The end of the pneumatic gripper 31 away from the rotating shaft 32 clamps and fixes the window control module. When conducting a waterproof test, the window control module is first placed in the clamping area of the pneumatic gripper 31. The pneumatic gripper 31 clamps the window control module. Then, the rotating cylinder 7 at the bottom of the housing 1 drives the rotating shaft 32 to rotate, causing the pneumatic gripper 31 and the window control module to rotate at a preset speed, so that the water flow of the spray component 2 can fully cover all surfaces of the module.
[0036] Preferably, the pneumatic gripper 31 is provided with an anti-slip silicone pad 8 on its inner side. The anti-slip silicone pad 8 is attached to the surface of the window control module to ensure that there is no displacement during high-pressure spraying.
[0037] A valve 9 for opening and closing the drain pipe 4 at the bottom of the housing 1 is provided. A water storage tank 10 is provided at the end of the drain pipe 4 away from the housing 1. The end of the spray pipe 22 away from the spray head 21 is connected to the water storage tank 10. When the spray test is performed, the valve 9 of the drain pipe 4 is opened, and the water in the water storage tank 10 is transported along the spray pipe 22 to the spray heads 21 on the top and side walls of the housing 1. The water is sprayed onto the surface of the window control module at a set pressure and angle. After the test, the water flows through the bottom of the housing 1 and collects in the drain pipe 4. It then flows directly into the water storage tank 10 through the opened valve 9. When the immersion test is performed, the valve 9 of the drain pipe 4 is closed, and external water is injected into the housing 1 through the water inlet pipe 5 until the water surface completely covers the window control module. After the immersion test is completed in a static water environment, the valve 9 of the drain pipe 4 is opened again, and the water in the housing 1 flows back to the water storage tank 10 through the drain pipe 4.
[0038] Preferably, a filter screen 12 for filtering impurities is provided at the bottom of the drain pipe 4 where it is connected to the housing 1. The filter screen 12 can effectively capture large particulate impurities in the test water and prevent them from entering the drain pipe 4 with the circulating water and causing blockage.
[0039] Furthermore, a buffer water tank 13 is provided on the spray pipe 22, located outside the water storage tank 10. The bottom end of the buffer water tank 13 is connected to the water storage tank 10 through the spray pipe 22, and the top end of the buffer water tank 13 is connected to the water pump 6 through the spray pipe 22. When a spray test is performed, the water in the water storage tank 10 is buffered by the buffer water tank 13 and then pressurized and sprayed out by the water pump 6, eliminating the influence of water level fluctuations in the water storage tank 10 on the water pressure of the water pump 6.
[0040] The implementation principle of this application embodiment is as follows:
[0041] When conducting a waterproof sealing test, the window control module is first placed in the clamping area of the pneumatic gripper 31. The anti-slip silicone pad 8 on the inner side of the pneumatic gripper 31 adheres to the surface of the window control module and clamps it. Then, the rotary cylinder 7 at the bottom of the housing 1 drives the rotary shaft 32 to rotate, causing the pneumatic gripper 31 and the window control module to rotate at a preset speed.
[0042] During the spray test, valve 9 of drain pipe 4 is opened. Water in water tank 10 is pressurized by water pump 6 on spray pipe 22 and sprayed out through spray head 21 on top and side wall of box 1 at set pressure and angle. Top spray head 21 sprays vertically and side wall sprays obliquely to cover the window control module, simulating natural rain or high-pressure car wash. After the test, the water flows into drain pipe 4 through open valve 9, passes through filter screen 12 to intercept solid impurities, and then returns to water tank 10 for recycling.
[0043] During the immersion test, valve 9 of drain pipe 4 is closed, and external water source is injected into the tank 1 through water inlet pipe 5. The water accumulates in the tank 1 until the water surface covers the window control module. After the test is completed in a static water environment, valve 9 of drain pipe 4 is opened, and the water in the tank 1 flows back to the water storage tank 10 through drain pipe 4 to realize the recycling of test water.
[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
